The relationship between gut bacteria and diseases could be overestimated

Many diseases related to bacteria, such as inflammatory bowel disease or colorectal cancer, are associated with an overgrowth of gut bacteria considered 'bad'. However, a study published in the journal Cell suggests that changes in microbial load, rather than the disease itself, could be the driving factor behind the presence of these harmful species associated with pathologies.

Metagenome sequencing of bacteria, fungi, and yeasts present in more than 2,500 foods

An international team with Spanish participation has developed a database with the metagenome of bacteria, fungi, and yeasts present in more than 2,500 foods, mostly dairy products, followed by beverages and fermented meats. The authors identified more than 10,800 microorganisms, half of which were previously unknown species. The study, published in Cell, shows that food-associated microorganisms are present in 3% of the adult gut microbiome and 56% of that of newborns.
